Benefits of technology

The patent is about a wired pipe segment that has a channel for transmitting data. This channel is formed by a transmission line channel that runs from the outer wall of the wired pipe segment to the inner bore of the pipe. The inner bore of the pipe has a pocket where an insert is placed to fill the empty space in the pocket. This design allows for secure and efficient data transmission through the wired pipe segment.

Problems solved by technology

In such cases, if the transmission lines are slack in the pipe segment, they may be damaged by fluids and debris flowing through the pipe segment.

Embodiment Construction

[0014]A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of example and not limitation with reference to the Figures.

[0015]Referring to FIG. 1, an exemplary embodiment of a portion of a well drilling, logging and / or production system 10 includes a conduit or string of drill pipe segments 14 (generally denoted as string 12), such as a drillstring or production string, that is configured to be disposed in a borehole for performing operations such as drilling the borehole, making measurements of properties of the borehole and / or the surrounding formation downhole, or facilitating gas or liquid production.

[0016]For example, during drilling operations, drilling fluid or drilling “mud” is introduced into the string 12 from a source such as a mud tank or “pit” and is circulated under pressure through the string, for example via one or more mud pumps. The drilling fluid passes into the string and is discharged at the bottom of...

Abstract

A wired pipe segment includes an inner bore extending through the wired pipe segment and a transmission line channel forming a channel from outside the wired pipe segment to the inner bore and including an inlet into the inner bore. The inner bore includes a pocket formed in the inner bore proximate the inlet and an insert is disposed in the pocket that substantially fills the pocket.

Description

BACKGROUND OF THE INVENTION[0001]During subterranean drilling and completion operations, a pipe or other conduit is lowered into a borehole in an earth formation during or after drilling operations. Such pipes are generally configured as multiple pipe segments to form a “string”, such as a drill string or production string. As the string is lowered into the borehole, additional pipe segments are coupled to the string by various connection mechanisms, such as threaded couplings.[0002]Various power and / or communication signals may be transmitted through the pipe segments via a “wired pipe” configuration. Such configurations include electrical, optical or other conductors extending along the length of selected pipe segments or string segments. The conductors are operably connected between pipe segments by a variety of configurations.[0003]One such configuration includes a threaded male-female configuration often referred to as a pin box connection. The pin box connection includes a mal...
